From Rome Reports:
The pope has also recalled the judgments of invalidity must respect the truth and justice of the facts and that they shouldn’t summit to societal pressure.
In particular, he said that all marriages are valid until proven otherwise. And that marital difficulties are not reasons to seek an annulment.
Apart from the grounds of marriage annulments, the Rota is the highest court of appeal for the Holy See. It is also responsible for judging the Church directly under the pope, like bishops and superiors of religious orders.
